重型缺口耙装有滑面轴瓦轴承。这种轴承由上、下轴承盖和轴套、轴衬(又称轴瓦)组成,其互相配合的轴套和轴衬都用冷硬铸铁制造,零件所有表面均不加工,而且要求不加工表面平整、光洁,硬度 HRC35～45。采用金属模型铸造重型缺口耙轴衬,可以满足零件硬度和表面平整的质量要求,适用于中小型工厂的批量生产。但由于该零件表面沟槽多,对开箱和脱模都带来了一定的困难。经过几年的实践,我们研

Heavy notch harrow equipped with sliding bearings. This bearing from the upper and lower bearing caps and bushings, bushings (also known as bearing) composition, its co-axial bushings and bushings are made of chilled cast iron, all parts of the surface are not processed, but also requires non-machined surface Smooth, smooth, hardness HRC35 ~ 45. The use of metal mold casting heavy notch rake bushing, to meet the parts hardness and surface roughness quality requirements for small and medium-sized factories in mass production. However, due to the surface of the groove parts, both unpacking and demoulding have brought some difficulties. After several years of practice, we research
